DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described in detail with reference to the illustrated embodiments.

As shown in FIG. 1, a device for raising aquarium fish according to the present invention comprises a water tank 1 having an upper opening, a lid L for covering the upper opening and consisting of an illumination mechanism housing 2 provided on the lower surface thereof with a fluorescent lamp (not shown) and a filtration mechanism housing 3 for filtering water, and a receptacle assembly 4. The filtration mechanism housing 3 includes a housing body 3a accommodating a filtration mechanism (not shown) therein and a lid member 3b for covering the upper opening of the housing body 3a. The illumination mechanism housing 2 and filtration mechanism housing 3 are disposed so that they cover the front side and rear side, respectively, of the upper opening of the water tank 1. The back upper portion of the housing body 3a of the filtration mechanism housing 3 accommodates therein a pump etc. (not shown) and has a notch 3c which serves as a fastening portion described later and through which electric cords (not shown) for the two housings 2 and 3 are led out. From the lower surface of the housing body 3a of the filtration mechanism housing 3, pipes and a strainer (not shown) project downward. The receptacle assembly 4 has an electric cord 5 passing out from the open side thereof and a plug 6 connected to the leading end of the electric cord 5.

As shown in FIG. 2, the receptacle assembly 4 comprises an assembly body 4a open at one side (on the bottom side in the illustrated embodiment), an assembly holder 7 fastened to the assembly body 4a by means of flanged screws 8 and serving as a fastened portion described later, a plurality of receptacles 9 accommodated in the assembly body 4a and connected to the electric cord 5 through lead wires 5a and 5b, and a receptacle cover 10 fixed by screws 11 to the inside of the assembly body 4a at a prescribed depth from the open side of the assembly body 4a for positioning and fixing the receptacles 9 within the assembly body 4a.

As shown in FIG. 3, the assembly holder 7 comprises a lateral wall portion 7a having two oblong holes 14 and a vertical wall portion 7b extending normal to the lateral wall portion 7a and having a central fastening hole 15 and has a substantially L-shaped cross section as a whole. The fastening hole 15 of the vertical wall portion 7b of the assembly holder 7 comprises a circular hole 15a and two vertical holes 15b and 15c extending to the circular hole 15a and having a width smaller than the diameter of the circular hole 15a. On the other hand, the receptacle body 4a is provided on the side opposite the open side with a recess 12 having a depth substantially the same as the thickness of the lateral wall portion 7a of the assembly holder 7 and a width generally the same as that of the lateral wall portion 7a and with two bosses 13 rising from the recess 12 and having a height substantially the same as the thickness of the lateral wall portion 7a. The bosses 13 on the recess 12 of the assembly body 4a are inserted into the oblong holes 7 of the assembly holder 7 and the flanged screws 8 are then screwed in the bosses 13 so that the assembly holder 7 is attached to the assembly body 4a slidably on the recess 12 within the range of the length of the oblong holes 14.

The assembly holder 7 is slidably attached to the assembly body 4a by means of the flanged screws 8 in cooperation with the bosses 13 and oblong holes 14. Therefore, the vertical wall portion 7b of the assembly holder 7 can be in contact with or spaced from the assembly body 4a of the receptacle assembly 4 as shown in FIGS. 4(a) and 4(b), respectively. The receptacle assembly 4 in the state shown in FIG. 4(b) can be fixed to the filtration mechanism housing 3 (as represented at 3a in FIG. 4B) at a prescribed position by inserting the vertical wall portion 7b of the assembly holder 7 into the notch 3c from which the electric cords (not shown) for the two housings 2 and 3 pass out and fastening the assembly holder 7 in the notch 3c.

FIG. 4(c) shows the receptacle assembly used in a different manner in which the assembly body 4a is attached through the assembly holder 7 to a wall W into which a screw S with a flange Sf has been screwed. The distance between the wall W and the flange Sf is substantially the same as the thickness of the vertical wall portion 7b of the assembly holder 7. In this case, the assembly holder 7 is provided on the assembly body 4a, with the direction of the vertical wall portion 7b changed from the direction thereof shown in FIGS. 4(a) and 4(b), and the screw S is inserted from the circular hole 15a into the vertical hole 15c of the fastening hole 15. The receptacle assembly 4 shown in FIG. 4(b) can attached to the wall W by inserting the screw S from the circular hole 15a into the vertical hole 15b of the fastening hole 15.

As has been described in the foregoing, according to the present invention since the receptacle assembly can be positioned and fastened on the filtration mechanism housing on the back side of the water tank by the assembly holder, the surroundings of the water tank become neat and the receptacle assembly is put out of sight. Furthermore, since the receptacles are directed downward and enclosed by the assembly body of the receptacle assembly, they are protected from water and prevented from short circuiting by water.

Since the assembly holder is slidably attached to the assembly body, the adjustment of the distance between the assembly body and the vertical wall portion of the assembly holder enables attachment of the receptacle assembly to filtration mechanism housing bodies of different thicknesses. Since the vertical wall portion of the assembly holder has the fastening hole, the receptacle assembly can be mounted at a place other than the device for raising aquarium fish.

While the illumination mechanism housing and filtration mechanism housing constituting the lid for the water tank in cooperation with each other are separate housings in the illustrated embodiment, they may be made integral. While the assembly holder is slidably attached to the assembly body in the illustrated embodiment, it may be stationarily attached. thereto. While the notch is formed in the filtration mechanism housing in the illustrated embodiment, it may be formed in the illumination mechanism housing or in an upper part of the water tank. While the notch and assembly holder serve respectively as the fastening portion and as the fastened portion in the illustrated embodiment, the fastening and fastened portions may be any means having a relation complementary to each other.
